CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Pat. App. No. 62/188,528, filed on Jun. 24, 2016, entitled “Retention Device,” the entire contents of which is incorporated herein by reference.

TECHNICAL FIELD

Embodiments of the invention are directed, in general, to valuables enclosures and, more specifically, to retention devices and methods of using the same.

BACKGROUND

Jewelry is small, valuable, and easy to lose. Because of its value, jewelry is often a target for theft. Active people may wish to remove jewelry during activities to prevent its damage or loss. For example, when working out at a gym or going for a run, an athlete may wish to remove jewelry to prevent personal injuries, or damage to the jewelry. One problem facing active people, is what to do with the jewelry once it is removed. If the jewelry is left in a locker it may be at risk of theft. If it is placed in a pocket it may be lost. Similarly, other valuables may be easy to lose and difficult to retain, including for example, medications, coins, etc.

Ring cases have previously been designed, but fail to adequately protect jewelry sufficiently to meet the needs of active persons. One previous ring case included a base and a standard over which a ring could rest. A portion of the standard included an abrasive material. The problem with this solution was than the ring case was not easily manageable or attachable to any sort of securing device, such as a clamp, clip, keychain, etc. Because the case was not substantially larger than the ring itself, the entire case and ring may be relatively easy to misplace. Additionally, the base did not lock into the cap. Rather, it simply screwed in to the cap, which could be easily displaceable.

Another prior solution involved a locket-type ring case attached to a necklace. This locket included a front and a back portion which were connected by a hinge. The front did not lock to the back with any sort of positive locking mechanism, which makes the locket-type case unsuitable for use in physical activities.

Another prior device included a ring case with a top and a bottom, which were simply pressed together. The bottom has a loop for attaching a keychain, etc., but does not operate to lock the top to the bottom in any way. Further, the ring case allows jewelry to move freely within the case, which can cause rattling, and or damage to the jewelry. For example, the rattling could loosen jewels or jewel settings, such as prongs on a ring. The ring case does not have the ability to hold jewelry in the ring case in a locked position.

SUMMARY

Embodiments of a retention device are described. In an embodiment, the retention device includes a retention base having a stem protruding outwardly from a first surface of the retention base. Additionally, the retention device may include a retention closure configured to engage the retention base, the retention closure having a hole for receiving the stem. The retention device may also include a receiver coupled to the stem, the receiver configured to receive a retention member for retaining the retention closure in engagement with the retention base.
